IMPROVED CLOTHES-WRINGER.

Specification forming part of Letters Patent No. 36,480, dated September 16, 1862.

To all whom it may concern.-

Be it known that I, H. W. PUTNAM, of Oleveland,in the county ofOuyahoga and Stateof Ohio, haveinvented certain new and useful Improvements'in Rollers for Wringing -Machines; and I do herebydeclare that the following is a fulland complete description of the construction and operation of the same, reference being had to the accompanying drawings, I making'a part of this specification, in which- Fig Us a perspective view. Fig. 2 is a sectional view.

Like letters of reference refer-to like parts in the two views.

' journals are first turned, and that part 'to be 1 covered by the rubber tubing is incased in a metallic mold, which fits accurately around the journals to 'prevent the escape of the melted metal, leaving a space on all sides ofthe iron I then pour into this mold an alloy of tin and zinc or lead and antimony,o r any other alloy that will melt at from 300 to 600 Fahrenheit, which in this manner completely in- I follows: The vulcanized rubber contains sulcases the iron shafts. Each end expands into a flange, G, forming the vcollar against which the ends of the rubber rest, as at E, Fig. 2.

' F is the rubber tubing, which is drawn over the flange G by means of a cone temporarily introduced upon the shaft A, the elastic tube retracting as soon asgit passes the flange. The

alloy casing B, by being coated with dissolved. india-rubbcr,' causes the cylinder and core to adhere permanently. g

1 The advantages of this improvement are as phur, which corrodes the iron shaft when the two are in contact in the presence of moisture, which soon loosens the rubber'fromthe shaft, but with my improvement this corroding will not take place, for the rubber is notin contact 1 with a metal that isreadily acted upon by the sulphur.

\Vhat I claim as my improvement, and desire to secure by Letters Patent, is-- Casting around the body of the iron shaft an alloy of metal with collars, substantially as de scribed, this alloy covering being interposed between the-iron shaft and the rubber covering, for the purpose of protecting the iron shaft from the corrosive action of the sulphur contained in the vulcanized rubber, as herein specified.
